Feasibility of an Intervention Targeting Health through Exergaming as an Alternative to Routine Treatment (FIT...

Despite elevated risk of cardiometabolic disease among those with serious mental illness, and widespread recognition that physical activity interventions are required, there are multiple barriers to implementing typically recommended physical activity programmes in secure inpatient settings. Due to low mood, negative symptoms and poor socio-occupational functioning, psychiatric inpatients often lack motivation to engage in physical activity programmes. Moreover, regular access to outdoor spaces and exercise equipment is limited. As such, there is a need for novel physical activity interventions that are suitable for secure settings. This study aims to investigate the feasibility, acceptability and potential effectiveness of an intervention (exergaming) to promote physical activity among patients in a secure mental health setting.

This non-randomised, two-arm pilot study will employ a pre-test/post-test parallel group design, comparing the exergaming intervention with a "routine treatment" control. Two high-secure, sub-acute wards in the Long Bay Hospital Mental Health Unit will be non-randomly allocated to either the exergaming intervention or the "routine treatment" control group. The intervention group will receive a 12-week programme comprising three 30-min exergaming sessions per week using various Xbox Kinect^TM activity-based games designed to simulate moderate intensity exercise. The "routine treatment" group will continue to receive the standard model of care delivered by the Justice Health and Forensic Mental Health Network. Accelerometers will be distributed to all participants to collect daily energy expenditure, number of steps taken, intensity of physical activity and heart rate data throughout the study. The primary outcomes are (1) intervention feasibility and acceptability, and (2) baseline to post-intervention changes in physical health outcomes (levels of physical activity; cardiovascular fitness; clinical measures of cardiometabolic risk). Secondary outcomes are baseline to post-intervention changes in mental health outcomes (depression, anxiety, stress, positive psychiatric symptoms). Outcomes will be assessed at baseline, mid-intervention, and post-intervention.

This research will contribute to evidence-based practice in the care of patients with serious mental illness: a vulnerable population with complex physical and mental health needs and a markedly elevated risk of cardiovascular disease. The findings will inform cardiovascular health promotion strategies and the implementation of physical activity interventions in secure inpatient settings.
